Did you find a solution for this issue?
Mine started occurring infrequently in Act 2, maybe once towards the end of the act, turned into 10 or so times in Act 3 and now in Arx it happens constantly.
Clearing Levelcache and deleting old saves works for a little but the issue always returns.
The amount of save files doesn't seem to be the issue because when it's working I can quicksave 30+ times with no issue. However when the crashes start occurring I need to delete levelcache and saves in order to be able to save again.
Tested nearly all fixes I've found online, I've even reinstalled the game.
Steamcloud disabled.
Created new profile and moved saves.
Disabled Onedrive (Uninstalled)
No AV
Lowered inventory size
No mods except bedroll and 8 AP from giftbag
Lowered settings
Lowered total save count
Another thing I've noted is that when enabled any other feature from the giftbag the game is guaranteed to crash on the next save, so I can't enable anything else.
I'm over 100 hours into my first playthrough and this is just so frustrating. Never had anything like this in BG3.
